(a) A person
operating a bicycle upon a roadway shall exercise due care when passing a
standing vehicle or one proceeding in the same direction. Bicyclists generally
shall ride as near to the right side of the improved area of the highway
right-of-way as is safe, except that a bicyclist:

(1) Shall ride
to the left or in a left lane when:

(A) preparing
for a left turn at an intersection or into a private roadway or driveway;

(B)
approaching an intersection with a right-turn lane if not turning right at the
intersection; or

(C) overtaking
another vulnerable user.

(2) May ride
to the left or in a left lane when taking reasonably necessary precautions to
avoid hazards or road conditions. Examples include objects on the road, parked
or moving vehicles, pedestrians, animals, surface conditions that may impair
the bicyclist's stability, or safety hazards caused by a narrow road or steep
embankment, road geometry, or unfavorable atmospheric conditions.

(b) Persons
riding bicycles upon a roadway may not ride more than two abreast except on
paths or parts of roadways set aside for the exclusive use of bicycles or
except as otherwise permitted by the Commissioner of Public Safety in
connection with a public sporting event in which case the Commissioner shall be
authorized to adopt such rules as the public good requires. Persons riding two
abreast shall not impede the normal and reasonable movement of traffic and, on
a laned roadway, shall ride within a single lane.
